[SOLVED] Laptop not booting anymore (Checking media presence)

Hi, I left my computer turned off for 3 days and now it doesn't boot anymore… I have arch installed on a luks-encrypted partition (with lvm on luks) so usually the first things that appears at startup is the prompt asking for luks password, but now I get:

>>Checking Media Presence…
>>No Media Present…

and then it automatically loads the BIOS screen.

What puzzles me is that I did not notice anything unusual during the last successful boot and did not perform any update. (The only problem I had recently was the clock randomly taking wrong values after resume/restart in the last months… I'm mentioning it because also the BIOS time seemed to be wrong, but not sure whether it can have any impact or not)

As it seems to be a problem with the boot image, I successfully chrooted and tried to update the mkinitcpio.conf (I noticed there was a .pacnew file that I had not seen before), ran a full system update including linux and linux-firmware. The problem is still here… Any idea where it can come from? Should I try to re-install grub even if I didn't change anything related to it recently ?

I have a boot partition and a luks-encrypted one with 3 lvm partition (root, home, swap), here is the result of `lsblk`:

Here is the mkinitcpio

(before updating it because of the .pacnew file, I had for reference the following:)

Re: [SOLVED] Laptop not booting anymore (Checking media presence)

I still don't know what happened exactly, but I was able to solve the problem by running again grub-install and grub-mkconfig. The grub entry was not listed in efibootmgr anymore for some reason.
